Nobody seems to care about the functionality of the percentage key, so I will be removing the app, there are lots more apps available that work! ### 1/5 — DO NOT DOWNLOAD IF YOU ARE A STUDENT *2020-11-26, version 2.3* I spent 25 mins on this garbage calculator only to realize the calculator was the problem and my equation was correct, I tried it on a different calculator and bam it was correct. I try it on this calculator and it gives the wrong answer. If you are a student and time is of the essence don’t use this terrible calculator. Absolutely garbage. ### 2/5 — Ugh!!! *2019-10-27, version 1.3* I can’t seem to find the fraction button which is really annoying!! Please come back to me to tell me where it is! ### 2/5 — Better than iOS calculator but buggy *2019-08-15, version 1.3* Cannot move the cursor around an expression to edit once typed in. Easy to max out the character/operations limit with long lists of figures like expenses, so you have to hit = every few operations. The decimal sign is not in the standard place for a numeric keypad which is really annoying! ### 5/5 — Very nice *2019-04-10, version 1.3* Not often I find a calculator on iOS with modulus built in, works as advertised.... its a calculator, and it’s free ### 2/5 — No Percent *2017-04-14, version 1.3* Percent doesnt work. Needed this for work which is visible aroumd guests and clients. Deleting now, whats the use of trying to wait for them to fix it when you need it now. Bye Felicia. UPDATE: 7 MONTHS LATER THEY RESPOND TO MY REVIEW. ### 1/5 — Doesn't do what's promised *2017-03-16, version 1.3* Disappointed wouldn't recommend. ### 4/5 — Great calculator but please fix the percentage error *2015-12-26, version 1.3* This is a calculator I looked for a long time. It has a very nice design. However, can I you fix the error of %. It shows error when ever I use this button. Thank you again for the app. ### 5/5 — Best Calculator on iOS *2015-12-03, version 1.3* Not only is this app beautiful, it's also highly functional. After searching through what must have been 20 calculators, I was ecstatic to discover this one. The developers are also very friendly and responsive, incorporating several suggestions into the app. I highly recommend this calculator! ## Frequently asked questions about SmartCalc Calculator ### Does SmartCalc have ads?

We took all the features you know and love, added a bunch more, and redesigned the app from the ground up! If you have a few moments of free time, we greatly appreciate any reviews. They help us grow our user base so we can continue to bring you feature-packed updates like this one. Thank you for all your support! Happy Holidays! ### 1.3 — 2015-12-02 We're back with another update! We redesigned the tip calculator and made a lot of small improvements that we think make SmartCalc even more seamless and intuitive. We also made a few bigger changes based on feedback from our fantastic users! Now, instead of tapping an expression or calculation to bring up the copy menu, you need to press and hold to bring up the copy menu. This change makes it a lot harder to accidentally open the copy menu when trying to pull down your history. We also added a new option to the copy menu. Or should we say, edit/copy menu! You can now select "Edit Expression" on any previous calculation to move the expression back into the edit window. We also changed how you backspace (yes, you could backspace before, but it wasn't very clear, so we fixed that!). Now, instead of swiping left on the current expression to backspace, there is a backspace button, and "floor", "round", and "ceil" have been moved to the function half of the calculator (accessible using the "2nd" key). And last, but certainly not least, if you press and hold any function or operator key, SmartCalc will apply it to the entire current expression. For example, if you enter "2+2", then press and hold "x", SmartCalc will display "(2+2)x". Or, if you enter "3x4", then press and hold "ln", SmartCalc will display "ln(3x4)". A long form example of this would be: "2+2", press and hold "x", "5", press and hold "ln" gives you "ln((2+2)x5)". We hope you enjoy the update! If you ever have any suggestions or feedback, please feel free to contact us at any time. And as always, if you enjoy SmartCalc and have a few moments of free time, we greatly appreciate any reviews.
